Geography of Expertise: Mapping the Knowledge Domain in Urban and Regional Planning in Nigeria

Abstract

Against the background of a critical gap in the systematic analysis of research focus and expertise distribution in urban and regional planning (URP), this study maps expertise within the field in Nigeria. The study analyzes diverse areas of specialization among 211 researchers
across 41 institutions through their Google Scholar profiles. It adopts a multi-facet analytical tools such as frequency analysis, VOSviewer, Location Quotients (LQ), and Geographical Information System (GIS) to examine the dominance and regional concentration of these areas of specialization. The findings reveal that the SouthWest region emphasizes housing (19%) while the North-Central zone focuses on urban governance (16%). In the North-East, research is concentrated on environmental planning (67%), whereas the South-South region prioritizes infrastructural and resource planning (25%). Despite these strengths, the study identifies critical research gaps, including a lack of focus on housing and land management in the North-East and insufficient attention to climate change and community development across all regions. The South-South also shows limited research on urban governance and management. Thematic clusters such as urban governance, housing, infrastructural planning, and environmental design highlight the interconnectedness of various specializations and the
need for integrated approaches. The study recommends diversifying research focus, promoting interdisciplinary collaboration, enhancing capacity building, and aligning research efforts with national and regional development priorities. By addressing these gaps and leveraging regional strengths, Nigeria can develop more effective and sustainable urban planning strategies. This study serves as a foundational resource for future research, policymaking, and academic collaboration in urban and regional planning in Nigeria.
